Dairy

Seaweed may be the super food dairy cattle need to reduce the amount of methane they burp into the atmosphere. Early results from novel research at the University of California, Davis, indicate that just a touch of the ocean algae in cattle feed could dramatically cut greenhouse gas emissions from California’s 1.8 million dairy cows.

Gene editing — one of the newest and most promising tools of biotechnology — enables animal breeders to make beneficial genetic changes, without bringing along unwanted genetic changes.

And, following in the footsteps of traditional breeding, gene editing has tremendous potential to boost the sustainability of livestock production, while also enhancing food-animal health and welfare, argues animal scientist Alison Van Eenennaam of the University of California, Davis.

Fresh, or raw, milk transported from farms to dairy processing facilities in tanker trucks contains a diverse mix of microbes, which varies from season to season, report researchers at the University of California, Davis.

Microbes with the potential to cause disease are destroyed during milk pasteurization, but not all bacteria and their associated enzymes are eliminated by that process. The remaining bacteria retain the ability to cause spoilage and quality defects in dairy foods.
